Commit 34f0f4e3f488 ("ibmvnic: Fix login buffer memory leaks") frees
login_rsp_buffer in release_resources() and send_login()
because handle_login_rsp() does not free it.
Commit f3ae59c0c015 ("ibmvnic: store RX and TX subCRQ handle array in
ibmvnic_adapter struct") frees login_rsp_buffer in handle_login_rsp().
It seems unnecessary to free it in release_resources() and send_login().
There are chances that handle_login_rsp returns earlier without freeing
buffers. Double-checking the buffer is harmless since
release_login_buffer and release_login_rsp_buffer will
do nothing if buffer is already freed.

The dwmac glue registers on Amlogic Meson8b and newer SoCs has two clock
inputs:
- Meson8b and Meson8m2: MPLL2 and MPLL2 (the same parent is wired to
both inputs)
- GXBB, GXL, GXM, AXG, G12A, G12B, SM1: FCLK_DIV2 and MPLL2
All known vendor kernels and u-boots are using the first input only. We
let the common clock framework automatically choose the "right" parent.
For some boards this causes a problem though, specificially with G12A and
newer SoCs. The clock input is used for generating the 125MHz RGMII TX
clock. For the two input clocks this means on G12A:
- FCLK_DIV2: 999999985Hz / 8 = 124999998.125Hz
- MPLL2: 499999993Hz / 4 = 124999998.25Hz
In theory MPLL2 is the "better" clock input because it's gets us 0.125Hz
closer to the requested frequency than FCLK_DIV2. In reality however
there is a resource conflict because MPLL2 is needed to generate some of
the audio clocks. dwmac-meson8b probes first and sets up the clock tree
with MPLL2. This works fine until the audio driver comes and "steals"
the MPLL2 clocks and configures it with it's own rate (294909637Hz). The
common clock framework happily changes the MPLL2 rate but does not
reconfigure our RGMII TX clock tree, which then ends up at 73727409Hz,
which is more than 40% off the requested 125MHz.
Don't use the second clock input for now to force the common clock
framework to always select the first parent. This mimics the behavior
from the vendor driver and fixes the clock resource conflict with the
audio driver on G12A boards. Once the common clock framework can handle
this situation this change can be reverted again.

Table 8-53 in the QUICC Engine Reference manual shows definitions of
fields up to a size of 192 bytes, not just 128. But in table 8-111,
one does find the text
Base Address of the Global Transmitter Parameter RAM Page. [...]
The user needs to allocate 128 bytes for this page. The address must
be aligned to the page size.
I've checked both rev. 7 (11/2015) and rev. 9 (05/2018) of the manual;
they both have this inconsistency (and the table numbers are the
same).
Adding a bit of debug printing, on my board the struct
ucc_geth_tx_global_pram is allocated at offset 0x880, while
the (opaque) ucc_geth_thread_data_tx gets allocated immediately
afterwards, at 0x900. So whatever the engine writes into the thread
data overlaps with the tail of the global tx pram (and devmem says
that something does get written during a simple ping).
I haven't observed any failure that could be attributed to this, but
it seems to be the kind of thing that would be extremely hard to
debug. So extend the struct definition so that we do allocate 192
bytes.

All the buffers and registers are already set up appropriately for an
MTU slightly above 1500, so we just need to expose this to the
networking stack. AFAICT, there's no need to implement .ndo_change_mtu
when the receive buffers are always set up to support the max_mtu.
This fixes several warnings during boot on our mpc8309-board with an
embedded mv88e6250 switch:
mv88e6085 mdio@e0102120:10: nonfatal error -34 setting MTU 1500 on port 0
...
mv88e6085 mdio@e0102120:10: nonfatal error -34 setting MTU 1500 on port 4
ucc_geth e0102000.ethernet eth1: error -22 setting MTU to 1504 to include DSA overhead
The last line explains what the DSA stack tries to do: achieving an MTU
of 1500 on-the-wire requires that the master netdevice connected to
the CPU port supports an MTU of 1500+the tagging overhead.

Pull powerpc updates from Michael Ellerman:
- Switch to the generic C VDSO, as well as some cleanups of our VDSO
setup/handling code.
- Support for KUAP (Kernel User Access Prevention) on systems using the
hashed page table MMU, using memory protection keys.
- Better handling of PowerVM SMT8 systems where all threads of a core
do not share an L2, allowing the scheduler to make better scheduling
decisions.
- Further improvements to our machine check handling.
- Show registers when unwinding interrupt frames during stack traces.
- Improvements to our pseries (PowerVM) partition migration code.
- Several series from Christophe refactoring and cleaning up various
parts of the 32-bit code.
- Other smaller features, fixes & cleanups.

The indirect block cleanup may cause control messages to be sent
if offloaded flows are present. However, by the time the flower app
cleanup callback is called txbufs are no longer available and attempts
to send control messages result in a NULL-pointer dereference in
nfp_ctrl_tx_one().
This problem may be resolved by moving the indirect block cleanup
to the stop callback, where txbufs are still available.
As suggested by Jakub Kicinski and Louis Peens.

This patch fixes an error condition triggered when the code path which
transmits a S/G frame descriptor when the skb's headroom is not enough
for DPAA2's needs.
We are greated with a splat like the one below when a SGT structure is
recycled and that is because even though a dma_unmap is performed on the
Tx confirmation path, the unmap is not done with the proper size.

The dpaa2-eth driver uses an area of software annotations to transmit

SWA structure has a different layout for each kind of frame that we are

Pull selinux updates from Paul Moore:
"While we have a small number of SELinux patches for v5.11, there are a
few changes worth highlighting:
- Change the LSM network hooks to pass flowi_common structs instead
of the parent flowi struct as the LSMs do not currently need the
full flowi struct and they do not have enough information to use it
safely (missing information on the address family).
This patch was discussed both with Herbert Xu (representing team
netdev) and James Morris (representing team
LSMs-other-than-SELinux).
- Fix how we handle errors in inode_doinit_with_dentry() so that we
attempt to properly label the inode on following lookups instead of
continuing to treat it as unlabeled.
- Tweak the kernel logic around allowx, auditallowx, and dontauditx
SELinux policy statements such that the auditx/dontauditx are
effective even without the allowx statement.
Everything passes our test suite"

On the Rx side, the next_to_use index points to the next item in the
HW ring to be refilled/allocated, and next_to_clean points to the next
item to potentially be processed.
When the HW Rx ring is fully refilled, i.e. no packets has been
processed, the next_to_use will be next_to_clean - 1. When the ring is
fully processed next_to_clean will be equal to next_to_use. The latter
case is where a bug is triggered.
If the next_to_use bits are not cleared, and the "fully processed"
state is entered, a stale descriptor can be processed.
The skb-path correctly clear the status bit for the next_to_use
descriptor, but the AF_XDP zero-copy path did not do that.
This change adds the status bits clearing of the next_to_use
descriptor.
